II. Product Classification and Characteristics
According to material, process, purpose and surface treatment method, steel wire products are mainly divided into the following categories, each with clear characteristics and applicable scenarios:
(1) Classification by Material
Low Carbon Steel Wire: With a carbon content between 0.10% and 0.25%, it is soft, tough, easy to bend and weld, and has moderate strength. It is mainly used for binding, nail making, weaving, agricultural fencing and other scenarios. It has high cost performance and is the most widely used basic steel wire variety.
High Carbon Steel Wire: With a carbon content between 0.60% and 1.20%, after quenching and tempering treatment, it has high strength, high hardness, good wear resistance and excellent elasticity. It is mainly used for making springs, steel wire ropes, cutting steel wires, rope-making steel wires, etc., and is suitable for industrial scenarios with high strength requirements.
Alloy Steel Wire: Made by adding alloying elements such as chromium, manganese, silicon and nickel to carbon steel, it has special properties such as corrosion resistance, high temperature resistance, high strength and fatigue resistance. It is mainly used in high-end fields such as machinery manufacturing, aerospace, chemical industry and medical treatment.
Carbon Steel Wire: Made of high-quality carbon structural steel without alloying elements, it has stable performance. According to the carbon content, it can be divided into low carbon, medium carbon and high carbon categories. Its uses cover various basic and industrial scenarios, and it is the core category of steel wire products.
(2) Classification by Surface Treatment Method
Black Steel Wire: Without surface treatment, the surface is covered with black-brown oxide scale, with low cost. It is mainly used for scenarios with low surface requirements, such as binding, nail making, temporary fencing, etc. Derusting treatment is required according to needs before use.
Bright Steel Wire: After pickling, phosphating, drawing and other processes, it has a smooth surface, no oxide scale, high dimensional accuracy and a clean appearance. It is mainly used for spring manufacturing, precision instruments, medical equipment and other scenarios with high surface quality requirements.
Galvanized Steel Wire: Divided into hot-dip galvanized and electro-galvanized, the surface is covered with a zinc layer, which has excellent corrosion resistance and can effectively extend the service life. It is mainly used in humid or corrosive environments such as building fences, power lines, agricultural greenhouses and marine engineering.
Copper-Plated Steel Wire: Plated with copper on the surface, it has both the strength of steel wire and the electrical conductivity and thermal conductivity of copper. It is mainly used in scenarios such as wires and cables, electronic components and communication equipment.
(3) Classification by Process
Cold Drawn Steel Wire: Formed by drawing at room temperature without heating, the product has high dimensional accuracy, smooth surface and high strength. It is the main current steel wire production process and is suitable for the production of various high-precision and high-strength steel wires.
Annealed Steel Wire: After drawing, it is annealed to reduce the hardness of the steel wire, improve toughness and plasticity, and facilitate subsequent processing such as bending and welding. It is mainly used for nail making, weaving, binding and other scenarios.
Oil-Quenched and Tempered Steel Wire: After drawing, oil quenching, tempering and other processes, it has high strength, good toughness and excellent fatigue resistance. It is mainly used for making high-pressure springs, auto parts, mechanical transmission parts, etc.
(4) Classification by Purpose
Construction Steel Wire: Including steel bar binding wire, scaffolding wire, prestressed steel wire, etc. It has high strength and toughness, and is used for building structure reinforcement, steel bar connection, scaffolding fixation, etc., to ensure the stability and safety of construction projects.
Industrial Steel Wire: Covering spring steel wire, cutting steel wire, welding wire, steel cord, etc., it is used in machinery manufacturing, automobile industry, metallurgy, chemical industry and other fields to meet the production and operation needs of various industrial equipment.
Agricultural Steel Wire: Mainly used for agricultural fencing, greenhouse frames, irrigation pipe fixation, etc. It is corrosion-resistant and anti-aging, adapting to the complex outdoor environment of agriculture and helping agricultural production.
Daily-Use Steel Wire: Including nail making wire, binding wire, cleaning wire, etc., with a wide range of uses, close to daily life, such as furniture fixation, item binding, cleaning and decontamination, etc.

V. Usage Notes
Selection Suggestion: Select the appropriate material and specification of steel wire according to the use scenario, force requirement and environmental conditions. For example, galvanized steel wire is preferred for humid environments, and high carbon or alloy steel wire is selected for high strength requirements.
Storage Requirements: Store in a dry, ventilated and cool warehouse, away from humid and acid-base environments, avoid outdoor stacking to prevent rust; coiled steel wire should be placed flat to avoid extrusion and collision, preventing steel wire deformation and fracture.
Usage Operation: Avoid excessive bending and stretching of the steel wire during use to prevent fracture; use professional tools when cutting the steel wire to avoid scratches on the hands by burrs on the cutting surface; when using steel wire for high-altitude operations, check the integrity of the steel wire to ensure no wear or cracks.
Maintenance: Regularly check the use status of the steel wire, and replace it in time if rust, wear, cracks and other problems are found; if the zinc layer on the surface of the galvanized steel wire is damaged, timely re-plating treatment is required to extend the service life.
